"It breaks my heart to tell everyone that Jarrod is no longer with us," Lyle's wife, Briony, said in a statement, per The Guardian.

He was diagnosed with acute myeloid leukemia last year and decided to stop receiving treatment last week.

"Earlier today Jarrod made the decision to stop active treatment and begin palliative care," Briony wrote in a Facebook post on July 31. "He has given everything that he’s got to give, and his poor body cannot take anymore. We'll be taking him closer to home in the next couple of days so he can finally leave the hospital

Lyle was first diagnosed with cancer when he was 17 and suffered a recurrence in 2012. He returned to golf in 2013, but the disease returned in 2017. He last competed on the PGA Tour in 2016.
